^This is my favorite forum for just that reason. I feel like there's a more knowledgeable community here than I've found anywhere else to date. In fact, while in most other forums and communities I happen to stumble across, I just jump right in and start posting if and feel right at home. Here, it took me literally a year before I could start posting what I felt was suitable material for this forum and even now, I still know I'm in the bottom 1/3 of the community when it comes to what I know and can contribute. However, the fact that I didn't feel comfortable enough to post didn't keep me from spending hours looking through each and every thread.
I know I'm not alone in that regard. Even now, there are probably some who are browsing but feel too uncomfortable to contribute; but that won't stop them from reading and admiring what this community offers in regards to knowledge of architecture, feelings on the current state of Boston and other cities, fascinating anecdotes, historical knowledge and trivia, etc.
